To all 'wwm 'it may concern: Be ,it known that I, FRANK P. Mms, a citizen of the United States, residing .at Chicago, in the county. of Cook and State of Illinois, have invented certain ne-w and uselful Improvements in Ain--Temperlng Devices, of which thefollowing is a specifica'- tion.

apparatus for purifying and tempering air and distributing the same 1n apartments, railway coaches, street cars,a nd thellke.

One ofthe objects of my lnvention 1ste 'provide' a system wherewith to supply properly purified and Atempered air to be distributed ,to apartments,. and whereby vitiated impure air may be taken therefrom 1n proport-ionately the'same extent as; the air is admitted thereto.

My invention consists further in the novel 'operation more' fully described hereinafter,I and shown 1n the accompanymg drawmgs.

In said drawings, Figure 1 is an elevation of the apparatus, partly in section; Fig. 2

is a plan view of the same with parts broken sleeping car, showing the registers at points of distribution with reference to the berthsof the car; Fig. 4 iS ,a lan viewof'the car on a reduced scale'gf F1g..5 is a plan view showing how theapparatus can be applied to an ordinary railway car apartment; and Fig; 61s a cross-sectional vlew taken on line 6-6 of Fig. 1, showing the pipe for con `air. e..

In Vall of the views, the same ,reference ducting the fresh airsurro'unded by thepipe for conducting the war'mer, foul, or vltlated characters indicate similar parts.

casing, 10p-rovided` with a series 'of compartments or chambers. The compartment 11 contains the fan connected to one end of the foul air pipe, 16,- and projects it through the foul air pipe 17, without the apartment.

The fan 18 `draws freshjair throughthe fresh air intake pipe, 19, which is preferably contained within the foul air pipe, .16. The

incoming air throughl the pipe 19 passesinto the chamber, 20, '.cont'ainlng water A porous diaphragm, 22, of such materlal as clot-h, divides the chamber or compartment My invent-ion relates to improvements in The apparatus consists generally vin thev 20 into two compartments, 2() and 20', -so that the airv coming into the compartment, 20, must pass` through the diaphragm, 22, which is preterably` dampened by water 21, into'the eye of the fan. The dust or material particles held in suspension in the incoming air, through the pipe 19, lodge against the porous diaphragm 22, and is thereby screened out, andthe air thus puritied. A distributing pipe, 2 3,is a means for y conducting -,the purified air tothe various points-of utillzatlon wlthm the several compartments. In Fig. 3,' I have shown this pipe located near the floor of a sleepingcar. The pipe yhas lateral branches, 231 and 23", which terminate in controllable registers. 24 and 24', respectively. The vitiated or foul air is taken out ofv the car by means ofthe pipe 16,1located near the roof thereof. The

foul. andv warm air entering the openings 25 and passing" through the pipe 16, 4contains considerable heat, and f' for this reason the pure airpipe is arranged within the foul air pipe, so that the heat of the foul air may be given up to the incoming pureair, and

thereby the incoming pure air will be tem- Y p'ered, or have its chill removed before it reaches the meansb,7 which it is to be subsequently heated before being distributed in the car. Any ordinary means for heating the air may be employed in connection with the system. After the foul air has passed through t-hepipe. 16,1and through the casing of the., fan, 15, it still contains some heat, and I therefore pass it through the chamber containing vthe water 21, so that the water may be-heated to some extent by the heat remaining inthe foul air before it is ejected from theapartment, thereby conserving all yof the heat to a useful purpose. The tem- "perature of the water,-21 being raised by this means, Vthe air through the pipe., 19, will "be somewhat warmed by it lbefore reaching vthe registers, 24e-24.

In 'very hot weather, when. 1t is desirable to cool` the air beforedistributing it to the various compartments .or sleeping berths of a car, I provide a casing, `26, which may be packed with rice. or otherwise cooled, as shown y. at 27.'

The distributing pipe 23 passesv through ,the casing, and the air pass- Fig. 5,v shows the apparatus deslgnedi for' an ordinary dwelling whereint-he fresh air pipe, 19, extends preferably tothe roof of the dwelling, from which location pure fresh air maybe taken and-passed down through the interior of the foul air pipe, 16, into the humiditying chamber, 20, and then into the fan chamber, 14, and thence to the disi to persons skilled in the tributing p pes 23, as shown and described with reference ltoFig. l.

In Fig. lis shown a .duplex apparat-us, one located at each end of the car, and the pipes of the respective apparatus confined to one side of the car. It will be apparent art that one apparatus could be, made to answer the purpose as well, and that the duplicate pipes 'may be extended to both parts of thej car if desired.

V'lhe duplicate apparatus, however, is more easily installed and occupies less valuable I claim is:

tributed to the sleeping berths.

Having described my invention, what 1. In a 4device of the character described,

necessary for the acat each end of the car a' a fan, for producingv an air current, 'a casing and pipin Iconnections including an inlet and an ex austportion through which said currentv is adapted to pass,.sa1d casing providing a water vchamber into the top ot which the air passes from said inlet port-ion, said exhaust portion passing through said water chamber below the water level therein,

whereby said-water may be warmed by thel relatively warm escaping air.

2. In a device of the character described,

a fan, a fan wheel for producing an air! current, ay casing,

througzll which said current is adapted Vto pass, one portion of said piping connections running within and encompassed by the 'other portion wherebythe air between said coacting portions and the air within the inner portion may tend to become equal in temperature, said casing providing a water chamber into which the air from one said portionof the' piping connections is drawn by said fan, the other 'portion passing chamber whereby theair therein may lend some of its heat to the water.

In testimony whereof I hereunto set my hand in the presence of two witnesses.
